3 Claims. l

This invention relates to a circumcision instrument of the so-called clamp or bloodless type, wherein the prepuce is tightly clamped between two members, after which the prepuce is cut in the proper manner.

An object of our invention is to provide a circumcision instrument of the bloodless type which can be quickly and easily positioned, and which can be efiectively and quickl held in clamped position, so that the surgeon may complete the severance of the prepuce.

The anterior end of the penis is called the glans, and is formed as an obtuse cone, and in section this cone would be an ellipse. The shape of the glans forms a rounded projecting border overhanging a deep rectro-glandular sulcus, and along the bottom surface of the glans, and extending also along the bottom of the corpus cavernosum urethrae is a nerve and cord bundle called the frenulum. If this frenulum is cut in the operation, sterility can result. It is therefore important that the frenulum be protected, and that the cutting of this frenulum be definitely avoided.

A further object of our invention is to provide an instrument in which it is impossible for the surgeon to cut the irenulum,

A feature of our invention resides in the shape of the cup which fits over the glans, the cup being so Shaped that the frenulum is avoided.

Other objects, advantages and features of in vention may appear from the accompanying drawing, the subjoined detailed description and the appended claims.

In the drawing Figure l. is a side elevation of our circumcision instrument with parts broken away to show interior construction.

Figure 2 is a rear elevation of the cup.

Figure 3 is a bottom plan view of the same.

Figure 4. is a longitudinal sectional view of the cup.

In the circumcision operation, the cup i is fitted inside of the prepuce, and is then fitted on to the anterior end of the glans. Since the glans is formed as an obtuse cone, it will be elliptical in section, and consequently the cup i is formed with a recess 2, which is elliptical in shape. The cup l thus must fit at an angle on the glans, and furthermore one side of the recess 2 is deeper than the other, as shown at 3. This shape of the recess in the cup i will result that the cup is placed at an angle on the glans, and consequently the bottom of the glans i which the frenulum appears will be avoided. As a further guard against the possibility of cutting the frenulurn, a vertical groove i may be provided in the cup The prepuce is now drawn around the cup l and the opening 5 in the base 6 is placed over the prepuce. The cup 5 is positioned within the opening 5 as shown in Figure 1, and the prepuce is clamped between the bottom belled por tion l of the cup 5 and the inner surface of the opening 5. It is necessary to clamp the prepuce tightly between the outer surface of the bell and the inner surface of the opening 5 so as to clamp oil the blood vessels in the prepuce. This clamping is accomplished as follows:

The cup l is provided with a stem 3, the stem being formed with two lateral lugs t. A lever it is pivotally mounted on the base it as shown at H. A finger E2 on the lever engages the lugs ii as shown in Figure 1, thus supporting the cup 2 in the position shown in Figure 1. The handle ii! and the base 6 are each provided with a serrated lock l3-li respectively, the serrated surfaces of these locks engaging to hold the handle it in its locked position, that is, where the cup i is tightly pressed into the Opening '5.

It will be evident that the clamping action of the instrument can be accomplished in one hand and once clamped, it will hold in that position until released by the surgeon. After the cup i has been positioned as previously stated and clamped on to the prepuce, the surgeon then cuts the prepuce around the flanged portion '1! of the cup to complete the circumcision.

Having described our invention, we claim:

1. A circumcision instrument comprising a base, said base having an opening in one end thereof, a handle pivotally mounted on the base, a cup adapted to fit in said opening, a stem rising from the cup, and means pivotally supporting the stern on the handle, said cup having an elliptical recess in the bottom thereof and a vertical groove in one side thereof.

2. A circumcision instrument comprising a base, said base having an opening in one end thereof, a handle pivotally mounted on the base, a cup adapted to fit in said opening, stem rising from the cup, and means pivotally supporting the stem on the handle, said cup having an elliptical recess in the bottom thereof and a vertical groove in one side thereof, one side of said recess being deeper than the other.

3. A circumcision instrument comprising a base, said base having an opening in one end thereof, a handle pivotally mounted on the base, a cup adapted to fit in said opening, a stem rising from the cup, and means pivotally supporting the stern on the handle, said cup having an elliptical recess in the bottom thereof and a vertical groove in one side thereof, one side of said recess being deeper than the other, and latching means between said base handle whereby the handle is held in its closed position.
